]]> NOAA Scientists Detect a Reshaping of the Meridional Overturning Circulation in the Southern Ocean /noaa-scientists-detect-reshaping-of-the-meridional-overturning-circulation-in-southern-ocean/ Wed, 29 Mar 2023 12:56:10 +0000 /?p=53047 Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) have shown that the Global Meridional Overturning Circulation (GMOC), commonly known as the global ocean conveyor belt, has changed significantly in the Southern Ocean since the mid-1970s, with a broadening and strengthening of the upper overturning cell and a contraction and weakening of the lower cell. These changes are attributed to human induced ozone depletion in the Southern Hemisphere stratosphere and increased carbon dioxide in the atmosphere. The study also shows that the changes in the Southern Ocean are slowly advancing into the South Atlantic and Indo-Pacific oceans.

Jennifer’s research spans climate science, physical oceanography, and coral reef ecology to better understand climate threats to reef ecosystems. She is now researching the influence of open ocean processes on mesophotic coral reefs using the biogeochemical Argo array in the Gulf of Mexico.

]]> The Spirit of International Cooperation Drives Oceanographic Discovery Aboard Tara /international-cooperation-drives-oceanographic-discovery/ Tue, 12 Apr 2022 16:24:17 +0000 /?p=30798 At 20:00 at 64°S in the austral summer month of February, the sun was still high in the sky. It cast a delicate light over the sea surface dotted with icebergs, which ranged from small misshapen chunks to massive angular structures with marbled cliffsides. In January and February 2022, I took part in an Antarctic voyage aboard the French schooner Tara. My participation was part of a partnership between NOAA and AtlantECO, a European-led consortium to characterize, quantify, and model Atlantic Ocean ecosystems.

The study found that global climate impacts on temperature and precipitation are projected to become more significant and persistent, due to the larger amplitude and extended persistence of El Niño in the second half of the 21st Century (2051-2100).

]]> Study Explores the Relationship of Anthropogenic Carbon and Ocean Circulation /relationship-of-anthropogenic-carbon-and-ocean-circulation/ Fri, 22 Oct 2021 15:54:07 +0000 /?p=26848 In a recently published study in Nature Geoscience, scientists at AOML and international partners quantified the strength and variability of anthropogenic (man-made) carbon (Canth) transport in the North Atlantic Ocean. The study found that buildup of Canth in the North Atlantic is sensitive to the Atlantic Meridional Overturning Circulation (AMOC) strength and to Canth uptake at the ocean’s surface.

]]> 2020 State of the Climate Report Shows Global Ocean Processes are Shifting /2020-state-of-the-climate-report/ Wed, 25 Aug 2021 19:17:12 +0000 /?p=25599 Today, August 25th, the 2020 State of the Climate report was released by the American Meteorological Society, showing 2020 to be one of the hottest years on record since the start of the Industrial Revolution. Even with environmental cooling factors, such as the transition from the El Niño of 2018-2019 to the La Niña of late 2020, global trends indicate the Earth is warming and sea level is rising. Throughout the report, environmental processes that influence climate and these warming trends are documented.

]]> Does the Risk of Vibrio Infection Increase in a Warming Planet? /vibrio-infection-in-a-warming-planet/ Tue, 10 Aug 2021 18:15:24 +0000 /?p=25017 In a recent study published in Lancet Planetary Health, Joaquin Trinanes, a scientist at NOAA’s Atlantic Oceanographic Meteorological Laboratory (AOML), uses a new generation of climate, population, and socioeconomic projections to map future scenarios of distribution and season suitability for the pathogenic bacteria, Vibrio. For the first time, a global estimate of the population at risk of vibriosis for different time periods is provided.
